Hey @hellcorpse,
It seems to me that DT really isn’t supporting magnet implants anymore, and I agree with them. The coatings are just not reliable enough atm to make it worthwhile. I had a TiN coated magnet put in a year ago and I’m already thinking about having it removed so I don’t have to deal with the inevitable repercussions of coating failure.
That said, I’d rather give you all the info I have so that you can at least do it safely, if you decide to move forward.
You can email Alex at Cyberise to see if he would be willing to ship to Brazil. You can also keep an eye on biohack.me, occasionally there is news there. Don’t settle for silicone, and please don’t try and DIY this.
